Patent GB-1280108-A (GB)
Title: Pipe coupler
IPC: F16L37/12
Filed: 1970-05-14
Abstract: 1280108 Disconnectable pipe joints YOUNGSTOWN SHEET & TUBE CO 14 May 1970 [23 May 1969] 23403/70 Heading F2G In a disconnectable pipe joint, clamping assemblies are adapted to engage and disengage a flange 19 on pipe 22, provision being made to release at least one clamp jaw 51 for rotation relative to the clamp arm 25 so as to effect quick disconnection. In one embodiment the arm 25 is pivoted at 27 to a screw threaded member 26 movable on lead screw 28. A peg 33, rigidly fixed with respect to the body 15 of the connector, runs in angled groove 32 such that on screwing the member 26 away from the joint the arm pivots clockwise to engage the jaw 51 behind flange 19 and draw the pipes together. On each arm 25 the jaw 51, pivoted at 52 to the arm 25, is prevented from rotating clockwise by a stop (61), (Fig. 5, not shown), and prevented from rotating anticlockwise by a roller 57, on the end of arm 53, engaging surface 55 on the jaw. Arm 53 is pivoted at 54 to arm 25, and is biased into engagement with the jaw 51 by spring 59. Actuation of an hydraulic piston 64 rotates arm 53 anticlockwise to release the jaw 51 from flange 19. The pistons 64 on each clamp arm of the connection are simultaneously operable, e.g. by a grease gun or other hydraulic source. In an alternative embodiment, Fig. 10, the jaw 75 is secured to at least one of the clamp arms 76 by pin 79 and an eccentric pivot 77. The eccentric pivot 77 is attached to a lever 78, normally in the position shown in full lines. To release the jaw the lever and eccentric are rotated to the position shown in dotted lines, thereby moving the jaw 75 slightly away from flange 19 to allow withdrawal of the pin 79. The jaw 75 then rotates freely about the pivot 77. Electromechanical operation of the release mechanism is also envisaged. In order to ensure liquid tight engagement of the pipe ends in the event of flange 19 being of non-uniform thickness around its circumference, an auxiliary member 93, Fig. 12, may be interposed between the pipe ends, one side of which is curved to accommodate misalignment with the coupling body 15. A plurality of different combinations of shape for the auxiliary member and the coupling body are given. This is particularly useful when the lead screws 81 are driven by a common ring gear 83, and therefore all move the same distance. The ring may be driven by one or more hydraulic motors 84. Alternatively, lead screws 28, Fig. 9, may be driven by separate motors connected in series such that each clamp applies an equal force despite unevenness of the flange 19. The coupling is particularly suited to provide a quick release connector on a loading arm for ships.

Title: Improvements in processes for improving the physical properties of austenitic alloy steels
IPC: C22C38/50
Filed: 1934-08-15
Abstract: In a process for improving the properties of austenitic alloy steels containing a precipitation hardening agent such as titanium or niobium, the alloy steel is quenched from a temperature above the recrystallization to normal temperature, strain-hardened, e.g. by cold working, and then subjected to a precipitation-hardening heat-treatment below the recrystallization temperature.  The precipitation-hardening temperature is carried out at 600-1200 DEG F., preferably at 850 DEG  F. for an alloy steel containing niobium, and may be of an hour's duration.  The alloy steels treated may be chromium-nickel steels, chromium-nickel-manganese steels or chromium-manganese steels, and the content of titanium 0,2-1,0 per cent and of niobium up to 3 per cent.  In an example, an alloy steel treated contains 18 per cent of chromium, 8 of nickel, not more than 0,2 of carbon and titanium 0,2-1,0, the latter content being preferably 5 times that of the carbon.  Beryllium, copper, silicon and tantalum may also be used as precipitation hardening agents and in amounts up to 3 per cent or a total of 3 per cent when more than one is used. In an example, an alloy steel treated contains 18 per cent of chromium, 8 of nickel, ,05 of carbon, ,40 of titanium, ,03 of sulphur, ,03 of phosphorus, ,7 of manganese and ,5 of silicon.  In the Specification as open to inspection under Sect. 91, cobalt, molybdenum, tungsten and vanadium may be used as precipitation hardening agents and also it is stated that the strain-hardening and the precipitation-hardening treatments may not be carried out in a single stage.  This subject-matter does not appear in the Specification as accepted.
